Interface PhysicsLinkable

All Known Implementing Classes:
AnimatedSprite, Sprite
public interface PhysicsLinkable

Implemented by anything a PhysicsBody can drive -- typically a com.codename1.gaming.Sprite. After PhysicsWorld#step(float) integrates the simulation, the world pushes each body's transform into its linked object through this interface, converting from physics meters to screen pixels and flipping the y axis so the linked object stays in screen coordinates.

Keeping the binding to this minimal interface (rather than a concrete Sprite) lets the physics package stay independent of the sprite/rendering layer.
